Landforms
Mountain chains are an example of:
Repeating landforms
A river system is made up of ______________ and _______________.
Weather determines ___________ temperature patterns.
Daily
A natural phenomenon is an event that takes place in __________________.
Nature
Global warming is a ______ increase in temperature of the Earth's surface that takes place over hundreds of years.
Slow
This theory explains how landforms are created.
Plate tectonics
The following drainage pattern looks similar to a tree root system.
Dendric drainage pattern
_______________ vegetation is the plant life that is native to a region.
Natural vegetation
Earthquakes, tornadoes, and _________________ are examples of natural phenomena.
Hurricanes
____________ species are non-native plants that can steal light, water and nutrients from soil. This type of vegetation is difficult to control and has government laws that determine which plants are allowed into the country legally.
Invasive species
This landform is formed when two plates collide and the top plate folds and is pushed upward.
Mountains
When water flows downward towards a larger body of water.
Drainage basin
Natural vegetation patterns are cause by the interaction of these two factors in the environment:
True or False: Natural Disasters can cause food shortages, habitat losses and crop damage.
True
Frozen earth will thaw. Polar bears may lose their ____________ to global warming.
Habitat
The three main types of landform regions in Canada include:
Lowlands, shield, and mountains
Name the two main river systems in North America
1. St. Lawrence 2. Mississippi
________________ currents flow in a circular motion. Warm currents flow away from the equator while cold currents flow towards the equator.
Ocean currents
It can take a) hundreds b) thousands of years for an environment to restore itself after a natural disaster.
Hundreds
Over time, the tundra will change to forest. Plant and animal life will either _________ to their new habitat or could become endangered.
Adapt
This theory explains why world landform patterns occur over millions of years.
Continental Drift
Give three reasons why rivers are important to people:
1. Food/Water 2. Farming 3. Transportation
Name two of the the six factors that affect climate:
1. Latitude 2. Air Masses 3. Global wind systems 4. Ocean currents 5. Altitude 6. Nearness to large bodies of water
This system monitors earthquakes on the ocean floor and provides people in the region time to move to higher ground.
Early-warning systems
If the tundra changes, global weather patterns can be further affected, releasing additional ________ _______ and _________ are into the air.
Carbon dioxide and methane
